Definitions
- the invention relates to a mechanical seal according to the generic part of the first claim.
- the invention has for its object to extend the technical application of mechanical seals, especially drive seals, to the effect that selbige for peripheral speeds above 10 m / s, in particular for peripheral speeds up to 30 m / s, can be used and capable of today common Radial shaft seals to replace significantly shorter life.
- This object is achieved in that at least the sliding surface of the sliding ring is provided with a convex contour.
- the mechanical seal only contains a sliding ring in operative connection with an elastomeric spring element, in which the sliding surface is provided with the contour according to the invention.
- the mechanical seal according to the invention can be used in use as a drive seal for significantly higher peripheral speeds up to 30 m / s and for this reason able to replace radial shaft seals with significantly shorter life.
- the respective contour is preferred by a polishing process or a
- the coatings can be DLC, PVD or
- Chrome layers on are on. Depending on the application, the person skilled in the art will select the suitable type of coating.
- the sliding ring is approximately angular in cross-section and has a radially extending sliding surface and a
- a drive seal consists in many cases of a sliding and a mating ring, wherein the sliding surfaces face each other.
- both the sliding surface of the sliding and the counter-ring is provided with the convex contour, it being particularly advantageous that the
- Sliding surface contours are formed substantially similar.
- the local surface pressure is significantly reduced and moreover also show advantages in possible
- Figure 1 schematic diagram of a consisting of sliding and mating ring
- Figure 2 partial view of the slide ring
- Figure 3 partial view of the sliding and counter ring
- Figure 4 Enlarged view of the sliding area between sliding and counter ring.
- Figure 1 shows a trained as a drive seal 1 mechanical seal, consisting of a sliding ring 2, a mating ring 3 and each an elastomeric
- FIG. 2 shows a partial representation of the sliding ring 2.
- the sliding surface 5 can be seen. In that region of the sliding surface 5 which is identified by an arrow, the sliding surface 5 is provided with a convexly shaped contour 7.
- the sliding surface 5 extends in this example in the radial direction and runs outside of the sliding surface 5 in a trapezoidal surface 8.
- Figure 3 shows in enlarged form the sliding ring 2, the counter-ring 3, the two sliding surfaces 5,6 and the trapezoidal surfaces 8.
- the provided with the convex contour 7 Gleit vomabites is surrounded by a circle.
- FIG. 4 shows, in a magnification of 50 times, the region 7 according to FIG. 3.
- the region 7 in this example in each case has a radius r, r ', which should be identical in this example. It is merely indicated that the sliding surfaces 5, 6 are provided with a coating, for example a chromium layer 9, 9 '.
